Hi guys,

Just came across this compressorhead video, spotted nixies @ 1:18

Yeah as I thought, I'll have to add something to the code for setting the 
time.

And well... Time is short (Christmas), interest is surely present. 

Two worst case scenarios: it is not ready and they receive a IOU a clock 
coupon instead of a clock *or *it never gets finished because my 
programming skills kinda suck. 

*doom scenario: things catch fire :P*

Re: [neonixie-l] Re: Arduino and MAX6921

[Adam Jacobs]

Time-setting as well as time-getting and displaying will need to be done 
on the Microcontroller.
The RTC relies on receiving an I2C message with the time to set; it 
doesn't have any mechanism for connecting buttons or such directly. 
'find out whether this is going to work' is probably something that 
depends entirely on the amount of interest & time you have. :)

Re: [neonixie-l] Re: Arduino and MAX6921

[Adam Jacobs]

Hi David,

I used to think it was strange too and always included the clock 
functionality in the microcontroller. However, I was always fine-tuning 
the accuracy. I believe that someone was posting to this list a little 
while back about his own Atmel microcontroller clock-code accuracy issues.


Later, I needed to build a clock that knew what day it was. I started 
putting thought into adding that to the microcontroller, how to account 
for leap-years, which months have how many days, etc. It was all more 
than doable, but I decided to use the opportunity to try using an RTC. 
Another driving factor was battery-backup. The RTC I was using (another 
from Maxim, can't remember the name but it is a 8-pin DIP) made battery 
backup a complete breeze. Real battery backup, a CR2032 or similar, with 
a total of months/years of battery life driving the RTC & TCXO.


The RTC I used was I2C and it also provided an opportunity to learn how 
to interface with I2C parts. :)
In the future, I'll probably use an RTC when I feel like it, on more 
complex clocks that have a smidge of extra space on the board and maybe 
could also use some reduction in microcontroller software size.


It is important to note that these builds are strictly for a hobby and 
not sale, so 'price is no object' provided that I can sample the parts 
for free. An RTC, TCXO and max6921 might total $25-$30 if I was doing 
this for sale, so that would be a non-starter. Of course, I've used 
those above parts as well as tons of other Maxim IC parts at work on 
larger projects. Maxim IC gets their money's worth out of me, I think. :)

I have always thought it strange when people do that. After all, the 
job of a microcontroller that runs a clock is to keep track of the 
time and make it show up on the display. Why add a second chip to keep 
track of the time when the micro is perfectly capable of doing that job?


Especially if someone has already written the code for you, unless 
they did a bad job of it.

Ah-ha! Good deal. I was assuming that your were in school studying 
electronics or microcontrollers, since you were posting to the group

Well, more and more, I think that electronics & software are extremely 
useful skill sets for anyone. Well, Electronics, Software & Law. But Law 
is outside the scope of discussion. :)
We have an employee here at work that joined as an intern (on a lark) 
during a break from her doctoral studies in biochemistry. She liked it 
so much that she stayed, changed her pending doctorate into an existing 
masters and joined the company full-time as a software engineer.

The datasheet tells us that the part is SPI (Serial interface),

The part of the code that you should be interested in is the part
that I cribbed from Limor's IceClock. Specifically, the
spi_xfer(), vfd_send(), setdisplay(). Setdisplay will definitely
need to be modified to suit your clock, but spi_xfer and vfd_send
are the 'voodoo' that you are trying to understand. Look at the
schematic in that file to see how SPI parts are electrically
connected to the microcontroller.

You mean using the milis function instead of a RTC?

Anyway, this looks like a good basis to me, I'm only missing the part that 
actually sets the time (I believe).

Maybe I should not be doing this kind of thing late in the evening I just 
noticed the attachment in this thread 
http://forum.arduino.cc/index.php?topic=159775.0 which gave me a complete 
piece of code. This made things a lot clearer and I have started 
"stripping" the code of things I do not need to make things easier. I will 
also add a RTC because for what they cost it seems like they make things a

need fixing but I think that the raw basis is there.

Lets put it like this, the only programming I ever do is a bit of LabVIEW. 
I'm doing a master in Bioelectronics and Nanotechnology but although it 
says electronics in the name, there is not too much "classic" electronic 
stuff. It mainly involves biosensor applications and cell membrane 
potentials which is a completely different branch of electronics. 

That your code is not in the arduino language but Atmel already explains a

friend of mine who is a lot better at written programming languages can 
help me a bit.

Re: [neonixie-l] Arduino and MAX6921

[Adam Jacobs]

Hi Gideon,
  What are you studying at university? We're starting to get to the 
point where you should be able to start figuring it out. Definitely 
shouldn't look like voodoo...


Start with the Datasheet:
http://datasheets.maximintegrated.com/en/ds/MAX6921-MAX6931.pdf

The datasheet tells us that the part is SPI (Serial interface), which 
means it is much easier to talk to than a I2C part. I'm not going to be 
able to help you with arduino, I've never used one. I always just 
program the Atmel microcontroller directly and use the part directly 
without the arduino bootloader/sketches business. To each their own. One 
of the huge advantages of the Arduino, though, is supposed to be the 
availability of community libraries to support these parts. I would 
maybe look a little harder or consider switching components to something 
that already has a community library written for it. I linked you the 
code/schematic to my VFD clock which uses a max6921. It's not arduino 
sketch, it is atmel microcontroller C code. I think that you should be 
able to figure it out.
Worst case, the arduino sketches are guaranteed to include support for 
sending a command via SPI.

The part of the code that you should be interested in is the part that I 
cribbed from Limor's IceClock. Specifically, the spi_xfer(), vfd_send(), 
setdisplay(). Setdisplay will definitely need to be modified to suit 
your clock, but spi_xfer and vfd_send are the 'voodoo' that you are 
trying to understand. Look at the schematic in that file to see how SPI 
parts are electrically connected to the microcontroller.

[neonixie-l] Arduino and MAX6921

[Gideon Wackers]

Well after all the great help with the hardware part of the arduino I have 
been looking at the code for my clock. For clarity I thought it would be 
better to open a new thread just about the software. 

What I want to make is a four digit clock with IV-11 VFD's that simply 
starts at 12:00 and starts running, no fancy menus or anything. Time will 
be set with two buttons; Button A increases the hours by 1, Button B 
increaes the minutes by 1. Pretty simply one would say but after looking at 
various other peoples code such as:

Re: [neonixie-l] Re: IV-11 VFD clock, some questions

[Gideon Wackers]

Yes it is very nice but also very smart. People will like you a lot more 
because of it and maybe that student that gets 10 dollar in samples today 
later orders shiploads of IC's from your company because he now designs 
equipment and remembers how nice those samples were. 

But now I am looking for some arduino code to drive the MAX6921, code seems 
sarce and the icetubeclock uses an older software version I believe.
